ROAD-DRAG.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed December 81, 1907. Serial No. 408,793.

To all whom it may concern:

Be it known that I, FRANK E. Orr,. a citizen of the United States, residing at Indian Marion and State of.

' road drag of improved construction that will be capable of use under various conditions and on roads constructedof various materials, a further object being to provide a .strong and durable road drag that will be adapted to be adjusted so as to operate equally Well on either hard or relative y soft roads surfaced either with earth or with gravel. T t

Withthe above-mentioned and-other obi'pcts in view that will become apparent ereinafter, the invention consists in an imroved drag com rising a frame having ownwardly exten ing pivot heads, blades of novel construction connected in novel manner to the pivot heads adjustment to various degrees of angularity,

. and improved adjusting and controlling tion consists further in the And the invennovel parts and arrangements of particularly described mechanism for the blades.

in the combinations and parts as hereinafter and defined in the appended claims. 40

Referring to the rawings, Figure 1 is a perspectiveview of the improved drag; Fig. 2 a rear elevation thereof with the operating lever broken away and the operators platform omitted; Fig. 3, a fragmentary transverse sectional view approximately on the line A in Fig. 2; and, Fig. 4,"a fragmentary near one longitudinal sectional view take end of the forward bladeon a plane correiponding approximately to the line B in Similar reference characters in the different figures of the drawings designate like ele' ments or features of construction.

1 The improved drag is preferably 0011- structed principally of standard sizes of iron or steel and comprises a draw-bar a of Slutbeams exten angle iron, and the beams c and c are A brace d is 8,137..

pair of pivot heads 71/ so as to be capable of I frame beams c and the middle ends of which are rlgiaiy 0 being secured, rigidly to ortion of the draw-bar, the (ling rearward approximately at right angles to the draw-bar, so that the beams band 1), two otherv beams are parallel one to another.- The beams are preferably composed of L- section spaced only a short distance apart. tached to the beam 6 and the draw-bar a,

and a similar brace d-'is attached to the draw-bar and to the beam 6, the braces bedisposed with respect to the ing diagonally draw-bar and the beams. A platform e is mounted on the beams b and c, and a plat form (2 is mounted on the beams b and c for supportin' the operator who may drive the team for ragging the implement.

The platforms may bec'omposed either of wood or metal and-also serve to stiffen ,the frame beams in their relative arrangement. The beam b has a pair of pivot heads f and f rigidly attached thereto, a pair of similar pivot heads g and being attached to the beam 12. t are attached to the beam 0, and a similar aITcN are attached to the beam 0, the pivot heads being arranged in pairs between the two beams. The pivot heads are all substantially alike and extend downward beyond the under sides of the beams, there being, as will be seen, four pivot heads arranged near the draw-bar a and four pivot heads arranged near the farther or rear ends of'the beams, and two blades 7' and 'j are provided-which may be composed of steel plate metal, relatively thin metal being suitable and therefore relatively: inexpensive by reason of the'construction adopted, the forward blade 7' having a'plate 7c secured to the rear side thereof-andthe blade 7" having a late 7c secured to the rear side thereof, the

ower edges of the plate having angle flanges Z and 1 respectively, extending therefrom rearwardly, the flanges being arranged approximately midway between the bottoms and the tops of the'blades j and 7', so as to thoroughly stiifen the blades and also being suitable preferably are employed as means for connecting'the blades to the frame beams of the implement, the arrangement being such that the li-eadsand near the under sides of the frame beams. The flange Zis provided with asuitable number of cars m, the flange Z having Another pair of pivot heads h and 7.

blades are forward of the pivot ears n 'and n rigidly attached thereto, the ears being adjacent to the pivot heads and 1 connected thereto by suitable ivots 0, each pivot preferably having a col ar thereon and held against rotation against the ear to which the pivot is connected in any suitable manner, each pivot preferably comprising a bolt having a nut thereon, and the eollar is designed to rotate in the pivot head in which the same is mounted, so that inexpensive machine work only is required in construction,

the object being to prevent accidental tighten ing of the ears against the pivot heads by means of the pivot bolts, and it will be obvious that shouldered bolts may be employed as equivalents of common straight bolts with collars thereon.

' ward blade are in alinement, and the pivots for the rear blade'are all in alinement, as will be understood, the lower ends of the arms 1) and 11 serving as supporting arms for pivotally connecting the middle portions of the blades as well as for adjusting the angularity of the blades, a connecting rod 8 being con- -ots s and s.

nected to the upper ends of the arms by piv- A quadrant tis mounted on the beam's'c and c and has notches t therein. A lever to is mounted also on the beams by means of a pivot 'v and is connected to the connecting rod 8 by a pivot '0, the lever at having a suitable latch at for entering either one of the notches t for latching the lever and preventing movement of the scraping blades on their pivots.

.The draw-bar a is provided with a pair of draft chains to and w, and a suitable number of apertures 90 and :0 to which the chains may be connected, as may be desired, by clevises y and 'y for connecting the chains to the draw-bar, each chain preferably having a ring 2 connected therein and a terminal ring 2, so that the draft animals, when two teams are employed, may be hitched toeither ring of either chain. When one team only is' employed for drawing the implement, it may be hitched to both terminal rings, or if desired to draw either end of the drag in advance of the opposite end, the team may be hitched to one terminal ring 2 and another ring 2 of the' other chain.

In .practical use, the lever a maybe moved to the position shown in Fig. 3 in order to set the blades so that the lower edges will be drawn in advance of the upper edges of the blades, the blades so adjusted being disposed to slightly cut into the surface of the road and suave off the higher portions, but when the surfareis toe soft for operating in this manner, the levcru may be adjusted at other angles, the extreme of its movement being shown in dotted lines in Fig. 3 in which position the, blades would slide over the surface of the road and drag the gravel or earth, so

that the higher parts wouldbe dragged into the lower places in the surface, and thus the Y surface may be made quite even and to the best advantage in operation.
